Not just for toothpaste: How fluoride enhances solar cells' performance
Inserting a metal fluoride layer in multilayered perovskite-silicon tandem solar cells can stall charge recombination and enhance performance, according to researchers at King Abdullah University of Science and Technology., the academics explain that tandem solar cells that combine perovskite and silicon-based subcells in one device are expected to better capture and convert sunlight into electricity than their conventional single-junction silicon analogs at a lower cost.
Liu and his colleagues systematically investigated the potential of other metal fluorides, such as magnesium fluoride, as interlayer materials at the perovskite/C60 interface of tandem cells. They thermally evaporated the metal fluorides on the perovskite layer to form an ultrathin uniform film with controlled thickness before adding C60 and top contact components. The interlayers are also highly transparent and stable, in line with the inverted p-i-n solar cell requirements.
The resulting tandem solar cell achieved a 50 millivolt increase in its open-current voltage and a certified stabilized power conversion efficiency of 29.3% —one of the highest efficiencies for perovskite-silicon tandem cells.
